RAILWAY-CROSSING.

To all whom it may. concern:

- Be it known thatI, CHARLES B. honour, a citizen of the United States, residing at 'Los Angeles, in the county of Los Angeles State of California, have invented certain new and useful Improvements in Railway-Crossings, of which the following is a specification.

' My inventionrelates to improvements in railway-crossings and frogs and especially crossings which ordinarily have gaps or recesses for the passage of the wheel flanges of the rolling stock of the road, and'where the corners of the crossings are apt to become defective and broken under I the pounding of the wheels.

It is an object of my invention to provide a crossing in which theflanges of the wheels raise the tread portions from the said crossing and eliminate all noise due to wheels jumping across the flange grooves.

It is a further ob ect of my invention to provide'replaceable wearing blocks or members at the intersecting corners of the said cross groovesof the crossing,"so that new corners may be set into the body of the crossing and secured by any simple means which is located at convenient positions on thecrossing and accessible without the removing ofthe entire crossing structure from the road bed.

It isa-still further object of my invention to provide a'crossing with a removable I groove section and to have the approaching end portions inclined, so that the flange of a wheel will roll up on the groove section gradually and raise the tread off the wheel off the crossing frame, thereby preventing the wheel from striking the corners of the grooves while the wheel passes thereby.

It is a still further object of my invention to cushion the replaceable groove and corner blocks or members with a soft but durable material, whereby the double wear upon the groove members and the corner blocks due to the wheels passing in different directions will be greatly reduced.

With these and other objects in view, my invention comprises certain novel constructions,

scribed and claimed.

In the accompanying drawing forming a 'part of this specification:

In'the accompanying drawingtwo forms of the invention have been illustrated and the details and "features of' the invention will now be more specifically described and claimed, referencebeing had thereto. In the drawing, 8 indicates the body portion or frame of a railroad crossing, the angle of intersection being represented as 90. The frame is provided with grooves 9 which have replaceable groove members 10 lying therein. These groove members are formed with the approaching ends as 11' and 12 being inclined, the inclination stopping at the edge of the recess 17, the intermediate distance as let being horizontal or parallel at the top of the frame of the crossing. The ends of these groove members are secured to the frame of the crossing by bolts 15 which may be welded or secured in any'other convenient manner; these bolts extend through the body portion 8 of the crossing and are tightened thereto by a nut 16. It will be observed that these groove members may be replaced at any time by loosening the bolt 15, whereby the said members may be detached from the frame of the crossing.

At the intersecting groove points are recesses 17 formedin the frame of the crossing, so that a detachable corner block 18 may be set therein above the groove member 10, as is clearly shown in Fig. 2 of the drawing. These groove' members are formed so as to make a continuous flange engaging member, and are held in the recess 17 by bolts 19 or in any other suitable manner, which may be later determined.

It will be observed that these corner blocks 18 do not extend in depth to the bottom of the groove member 10, but are of "occurs due .to the "wheelsrolling in "both" ample depth to insure the" proper strength required at'the intersections of the grooves where the double wear upon the crossing directions. 7 I

It will also be observed'that the inclination 11 of the groove members is so gradual. that there is no danger of a wheel 'jumping when the flange begins to roll up .upon the groove members. The bolts 19'are' so placed with respect to the grooves that-they can not be touchedby the tread of a wheel asthere is amplexdistance between :them and the edge of the adjacent groove.

It will also be observed-thatthe bolts which are shown welded to'the groove members in this particular instancesare beneath the grooves and. entirely away-Tirom' the flange oft-he wheel. 1 v

In the modified form shown in Fig! 15 WhlCh' I'GPIYGSGIItSH portionof a crossing or a frog, vthe detachable groove member 20 has a block 21 seated therein intheforni of a cross; this blockis c'letachableand held in place by any suitable means as a bolt 22. By making the form of this block the'shape of a cross, it will be observed that asthe flange of the wheel-travels in both directions across this intersecting point, the wear' on said block is twice as muchas at any intermediate point and may be'xreadily replaced; 'Between the under surface. 23 of the groove member 20 andthe frame "24 is a cushion member 25 madenp of a soft durable ma ter-ial'such as silk, or other fabric whereby the groove member 20 and the corner block 21 setting in saidgroove may bexcushioned so: as to overcome as much wearv as possible upon the groove member. Formed in: the frame of the'crossing 24 is a holeoropening 26; which .alloivsthe head of the' bol-t'22 to set thereinwhereby thercorner may be replaced by loosening the nuts 270i the said bolt 22. Bythis construction itjwill be observed that the corner block, groove member andcushioning material is rigidly held to:

gether and may be replaced at any time. The replaceable parts of the crossing have crossing structure from the road bed, there being ample room for any workman to loosen the securing means of the said parts fronr the uppersurface of the crossi-ngstructure. The groove n embers and corner blocks been so! designed as tobe changed at any time without completely' removing the whole have theiredges curved upwardly as at 29.

device may be varied, and; mechanical equivalents substituted therefor withiiiit departing from fit/he 5 spirit :of the invention. The openings 28 in the centerof the crossing; may :be covered by .a plate if it is iiound necessary atcentain locations wherethiesaid crossing is to be installed.

Having thus described my invention what I'claim isz' i 1.. A no seless; i iall'way crossing hav1ng grooves, formedfitherein, .fla'inge} engaging members lyingv in said grooves, replaceable wearing corners adapted toibe :set In said members, theapproachingwend portions of said flangeengaging-members being inclined upward toward said wearingeorners.

A noiseless railway crossing -.having flange grooves, formed therein, detachable flange engaging members --seated in sa id grooves; corner blocks set into said members, means for securing said-flangeiengaging members in said grooves, and means for detachabilysecuring the said corner blocks in said flange engaging members. I" In testimony whereof, I have-hereunto set my hand.. a
